Disque is a distributed memory message agent Salvatore Sanfilippo, the father of Redis, is a new open source. It adapts to the "Redis as Job queue" scenario, but employs a dedicated, standalone, extensible, fault-tolerant design that combines the simplicity and performance of Redis with the C language as a non-blocking network server.Redis the author Salvatore

Memcached or Redis? This has been a controversial topic in modern high-performance Web applications. When Web applications that are based on relational databases need to improve performance, using caching is the first choice for the vast majority of architects, and naturally, memcached and redis are often preferred.Common features Memcached was originally developed by Brad Fitzpatrick for the LiveJournal website in 2003. And then rewrite it again in C (the
ideal buffer layer implementation scheme. From a performance perspective, the two types of data storage mechanisms also have a number of commonalities, including the ability to have almost the same characteristics (and metrics), and a high degree of attention to workload data throughput and latency.In addition to the same in-memory key-value data storage scheme, memcached and Redis are also very mature and popular open source projects.

It has the following features: the overall structure of Redis is a single-threaded server (except for writing a disk to open sub-processes, VM management to open threads, ignore these two blocks first, its server startup process is very clear.

The current stable version of redis (2.0.4) only supports Simple master-slave replication: one master write, multiple slave reads. Sharding can only be performed by the client through consistent hashing. Redis cluster is the focus of development in the next version, including automatic sharding of the cluster, multi-node fault tolerance, and so on.

Salvatore Sanfilippo, the author of Redis, has compared these two memory-based data storage systems in general and is relatively objective, and is summarized as follows: 1) performance comparison: Since Redis uses only single cores, and memcached can use multicore, So on average, Redis has a higher performance than memcached for storing small data on each core. In more than 100k of data, Memcached performan
One of the great benefits of Redis is that you can use databases such as MySQL instead of the entire database, but only in some specific scenarios to improve efficiency through Redis's features.

Redis's author, Salvatore Sanfilippo, once compared these two types of memory-based data storage systems: 1.Redis supports server-side data operations: Redis has more data structures and supports richer data operations than memcached, usually in memcached, where you need to get the data to the client for similar modifications and set back. This greatly increases the number of network IO and the volume of d
